Compare 1 Pet 2:9; Rev 1:6; 5:10. What under law was conditional is, under
grace, freely given to every believer. The "if " of v. 5 is the essence of law
as a method of divine dealing, and the fundamental reason why "the law made
nothing perfect" (Heb 7:18 - 19; cp. Rom 8:3). To Abraham the promise preceded
the requirement; at Sinai the requirement preceded the promise. In the New
Covenant the Abrahamic order is followed (see Heb 8:8 - 12, note).

Exo 15:26; 23:22

Ps 78:10

The Mosaic Covenant, given to Israel in three divisions, each essential
to the others and together forming the Mosaic Covenant, i.e. the commandments,
expressing the righteous will of God (Exo 20:1 - 26); the judgments, governing
the social life of Israel (Exo 21:1 - 24:11); and the ordinances, governing the
religious life of Israel (Exo 24:12 - 31:18). These three elements form "the
law," as that expression is generically used in the N.T. (e.g. Mat 5:17,18). The
commandments and the ordinances formed one religious system. The commandments
were a "ministry that condemns" and "brought death" (2 Cor 3:7 - 9); the
ordinances gave, in the high priest, a representative of the people with the
LORD; and, in the sacrifices a cover (see Atonement, Lev 16:6, note) for their
sins in anticipation of the cross (Heb 5:1 - 3; 9:6 - 9; cp. Rom 3:25 - 26). The
Christian is not under the conditional Mosaic Covenant of works, the law, but
under the unconditional New Covenant of grace (Rom 3:21 - 27; 6:14 - 15; Gal
2:16; 3:10 - 14,16 - 18,24 - 26; 4:21 - 31; Heb 10:11 - 17). The law did not
change the provision of the Abrahamic Covenant but was an added thing for a
limited time only - till the Seed should come (Gal 3:17 - 19).
For notes on other major covenants, see: Edenic (Gen 2:16); Adamic (Gen 3:15);
Noahic (Gen 9:16); Abrahamic (Gen 12:2); Palestinian (Deu 30:3); Davidic (2 Sam
7:16); New (Heb 8:8).
